Xiaomi devices and Battery Optimizers - Boomerang

Background

Some device manufacturers use a non-standard method to save battery by essentially killing any App that should be set to work in the background so this removes the permissions that we need. 

Xiaomi is notorious for their aggressive battery optimization so we have to exempt Boomerang Parental Control (for kids) or Manage SPIN (for adults) from this aggressive battery optimization.  Thankfully, Xiaomi does provide a method to have the permissions "stick." 

Solutions

Activating the Accessibility Permission:

On some Xiaomi devices, during install, the ability to toggle on the Accessibility permission from the install wizard will not "link" correctly.  In these cases, activate it manually by going to: Settings > Additional settings > Accessibility > More downloaded services > Boomerang Accessibility: Toggle On.  Then restart with the install process.

Set Permissions:

Depending on the Xiaomi device, these solutions may differ slightly and not all Xiaomi devices will have all three solutions.  Check your device for in the following areas based on these three solutions:

Solution 1:

Go to: Settings >Apps > Permissions > Other Permissions > Boomerang
Then Enable the following:
- Display pop-up windows while running in the background
- Display pop-up window
- Permanent notifications.

Solution 2:

Go to:  Settings > Search "Security" > Settings > Booster Speed > Boomerang: Toggle On.

App Security

On Xiaomi devices, for enhanced security, we need to "lock" Boomerang.  Here are the steps:

• Open Boomerang App
  
• Now, tap on the Recent Apps Dialog button
  
• Press and hold Boomerang's card and "lock" Boomerang

Check: Make sure Boomerang now has a "lock" icon after it's name on the Recent Apps Dialog

Older Models: The settings may be in slightly different places:

• Device Settings > Advanced Settings > Battery Manager > Protected apps – Boomerang needs to be Protected
• Device Settings > Apps > Boomerang > Battery > Power-intensive prompt and Keep running after screen off
• Settings > Additional Settings > Battery & Performance > Manage apps’ battery usage and here:
  1. Switch Power Saving Modes to Off
  2. Choose the next options: Saving Power in The Background > Choose apps > select your app > Background Settings > No restrictions

Security on Older Models: Certain Xiaomi devices do not have the ability to "lock" an App and have it protected from the Recent Apps Dialog so use Boomerang's Advanced feature to block the "Recent Apps Dialog" entirely.

• Login into the Boomerang Web Management Dashboard located at: https://app.useboomerang.com/My and then click on the child device and then the Advanced Tab.  Here, check the "Block Recent Apps Dialog"
